1. A rotor assembly for a blow-through rotary valve, the rotor assembly comprising:
a drive shaft defining a drive axis along its length;
at least one chamber operatively connected to the drive shaft, the at least one chamber comprising a first end wall and a second end wall, the first and second end walls being axially spaced along the drive axis;
a first side wall and a second side wall, the first and second side walls extending substantially laterally from the drive axis, the first and second side walls extending substantially parallel to the drive axis,
wherein the at least one chamber defines an opening at or towards a radial outer portion of the at least one chamber,
wherein the at least one chamber is asymmetric along a plane containing the drive axis, and
wherein the first end wall and the second end wall together define a concave surface which is configured to be in contact with material to be loaded and unloaded in the rotor assembly so that the at least one chamber stimulates a vortex flow when the opening of the at least one chamber is in contact with a gas flow.
